Date Picker - placeholder

[drandell]

More of a question than any particular bug. The documentation shows a placeholder for the date picker: https://pub.dev/packages/fluent_ui#date-picker

But me doing the same following the example :

// property.date is set to DateTime.now()
Row(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: [
              Expanded(
                  child: Padding(
                      padding: const EdgeInsets.only(left: 5),
                      child: DatePicker(
                        header: property.label,
                        onChanged: (v) => setState(() => property.date = v),
                        selected: property.date,
                      )))
            ]);

Gives me the current date with no placeholder.
Since I can't set the selected value to null, is that screenshot/gif correct in the documentation?
